DEVICE F018 USE IN THE ATTACHMENT SLTNGS TE) HJITBTIBTG Applicationfiled November 1?. 1819. Serial No. 335,671.

5 land, New Zealand, have invented a new and useful Improved Device forUse in the Attachment of Slings 'to the Hoisting Means; and I do herebydeclare the following to be a full, clear, and exact description of thesame.

This invention has been devised in order to provide a substitute for theordinary type of sling hook used in the hoisting of goods in shipsslings and for other analogous purposes. The device now designed forsuch purposes does away with the objection to the use of the ordinaryhooks by reason of their liability'to catch on any impediment with whichthey may engage while swinging, and at the same time provides for thesling, whether of rope or chain, being effectively held upon thehoisting or suspension means.

The device consists in an elongated link, at one of its ends having aneye or other means for its attachment to the suspension wire or cable,and at its. other formed with a tongue extendinglongitudinally with thelinks length, from the centre line thereof downwards for an appro eddistance. This tongue at its bottom. end is formed with a large roundknob. If necessary, the lower end of the link may be thickened aroundthe neck of the tongue.

In the accompanying drawings :-a

Figure 1 is a front elevation of the device.

Figure 2 is side elevation thereof. 7

Figures 3 and 4 are respectively similar views with a sling in engagingpo 'tion thereon. I

A is the link having at its upper end an eye shank B for its attachmentto the hoisting cable. 0 is the tongue extending from specification inthe presence the lower end of the link in a line continuthe centre linethereof, and D is the knob with .vhich such tongue ends.

in use, sling G is att ched to the device by passing the bight or loopthereof through the l ink, carrying it round and'under the end andloopin it over the knob D so that it surrounds the tongue G. Then whenthe weight placed on the sling, the loop around the tongue is drawntight and the weight carried by the link. It is impossible for the slingto slip 01? the tongue so long the wei remains upon it, as the knob ismade sui ently large to hold it and most of the strain on the loop is anup-- ward direction around "the tongue. When the strain is relieved. thesling may be easily and quickly detached.

The lower end of the link A is preferably made wider than the no Jer endas shown in A 7 rligures i "Ilfl 8 its lnncr edge formed with the uponopposite con cavities -J sides or" :1 central projection F in which therespective nimnbers oi the sling bight or loop will fit. This will serveto prevent any jamming oi? the slii in the link and any tendency for onemember or the bi ht to ride on the other.

I claim 2-- A link for a achment to a cable and provided at the endopposite the cable with an inwardly extended projection and also with anoutwardly projecti tongue having a head at its outer end and spaced fromthe link.

In testimony whereof, I have signed this of two subscribing witnesses.
